Polymers are getting attractive in electronics due their flexibility, low-cost synthesis process and easily manipulating molecular design and morphological structures with choice of applications. Therefore, our one of the key materials for our different applications is polymeric materials or mainly conjugated polymers. Our team for last 10 years  are developing this type of materials with different nanostructures and on different types of substrates. We have already used simple rigid substrates like glass, silicon, ITO coated glass to super flexible substrates like textile yarns, carbon fibers, PET and cellulose substrates. Also, our team has prepared different nanostructures of polymeric materials for their different applications. 

Charge Transfer Mechanism

Conjugate polymers are of great interest because of their ability to control the energy gap and electronegativity through molecular design that has made possible the synthesis of conducting polymers with a range of ionization potentials and electron affinities. The excellent properties of π-electron delocalization at the backbone of conjugated polymer ( ex. Polyaniline, Polypyrrole, PEDOT, P3HT, etc.) can be the initiator of charge transfer mechanism that can be employed in multifunctional smart applications. The aim of our research interest is to develop different nanostructures conjugated materials with modified electrical properties for our choice of applications.

Smart Textile (SMARTEX)

Our mission of the scientific development is the unification of three significant sectors  which is Energy, Information Technology and Textile in a sustainable way while delivering a long-term benefit: a new conception of SMARTEX (smart textile) economy which is essentially based on green, sustainable and circular economy. We are designing and building textile based wearable energy generator, targeting accumulation of energy dissipated by the daily body movement into the electrical energy that would be smart, interactive and connected with Internet of Things.

Electronic Paper (e-Paper)

According to U.N sustainable goals and European Green Deal, another challenge in the digital industries is to promote minimum electronic waste (e-waste) generation after the expiry of product .  In Portugal, each year 63 thousand tons of e-waste is produced, among those only 15-20% is recyclable. In this context, the European Union alone produces more than 2.5 billion tons of waste each year, from which only 36% is recycled. Giving priority to these global challenges, We are constructing our research programm in such a way that will buckle bio-compatible materials and self-powered electronic platform to bring a new game-changing idea while promoting a circular economy simultaneously. The project will work on sustainable technology that will run on renewable energy and emphasize on reusable materials platform.

Nanoscale Data Storage

The increasing demand for miniaturization in microelectronics has led to an upsurge interest in developing nanoscale electrical characterization as a part of the effort to enhancing nanoelectronics. In
that context, we are working on the study of direct visualization of charge propagation through the organic/inorganic nanostructures via nanocontact probe induced charge (both positive and negative) injection method through AFM The experimental works open a way for ‘writing reading’ of memory bits using electrical bias towards the development of next generation charge trapping data storage devices with establish of smallest bits memory cells The core idea of this device is charge patterning through charge trapping mechanism, which is visualized further by the subsequent electrical mapping

Bio-waste Derived Materials

In recent years, there has been burgeoning interest in waste management systems as the concept of sustainable development is a subject to criticism. Reduce, reuse and recycle are three basic building factors in this regard which can accelerate the transformation towards sustainable development goals for post fossil-carbon society. In that context, Our experimental findings impart a new possibility of using waste carbon from cooking oven in the application of multi-purpose  smart applications by incorporating it within polyaniline matric in a green route. A simple and effective impregnation method has been adopted to embed carbon nanoparticles into polymers without any coupling agent or complicated pre-treatment. We have already reported this types of smart materials towards different applications, such as data storage, photolumunuscence, supercapacitors and electrorheology.
